windows - 在Windows cmd中，如何提示用户输入并在另一个命令中使用结果？(In Windows cmd, how do I prompt for user input and use the result in another command?)

Question

I have a Windows .bat file which I would like to accept user input and then use the results of that input as part of the call to additional commands.

(我有一个Windows .bat文件，我想接??受用户输入，然后使用该输入的结果作为调用其他命令的一部分。)

For example, I'd like to accept a process ID from the user, and then run jstack against that ID, putting the results of the jstack call into a file.

(例如，我想接受来自用户的进程ID，然后针对该ID运行jstack，将jstack调用的结果放入文件中。)

However, when I try this, it doesn't work.

(但是，当我尝试这个时，它不起作用。)

Here's my sample bat file contents:

(这是我的样本bat文件内容：)

@echo off
set /p id=Enter ID: 
echo %id%
jstack > jstack.txt

and here's what shows up in jstack.txt:

(这是jstack.txt中显示的内容：)

Enter ID: Terminate batch job (Y/N)?

Answer 1

Try this:

(试试这个：)

@echo off
set /p id="Enter ID: "

You can then use %id% as a parameter to another batch file like jstack %id% .

(然后，您可以使用%id%作为另一个批处理文件的参数，例如jstack %id% 。)

For example:

(例如：)

set /P id=Enter id: 
jstack %id% > jstack.txt
